1 Introduction
Because a lawn mower is a high-speed cutting 
tool and is battery-powered, special safety 
precautions must be observed to reduce the risk 
of personal injury.
Read this instruction manual thoroughly before 
use and periodically thereafter. Follow all safety 
precautions. Careless or improper use of the 
lawn mower can cause serious or fatal injury.
